Referring to FIGS. 6, 7, 8 and 11, once the user presses down the hand press lever 11, the actuating rod 12 can drive the second extendable air pump 26 and the third extendable air pump 27 to extend downward and expand the volumes thereof. At this time, the outside air can open the unidirectional valves 261, 271 to enter the second extendable air pump 26 and the third extendable air pump 27 as shown in FIG. 6. When the user raises the hand press lever 11, the actuating rod 12 drives the second extendable air pump 26 and the third extendable air pump 27 to reduce the volumes thereof. Right at the time, the unidirectional valves 261, 271 close respectively and the air in the second extendable air pump 26 and the third extendable air pump 27 is compressed to flow toward the first intake pipe 252 and the second intake pipe 254. The air in the second intake pipe 254 further flows into the first intake pipe 252. Right at the moment, the air pushes through the unidirectional valve 255 to enter the first extendable air pump 25 and the first extendable air pump 25 extends to compress the compression spring 24. Meanwhile, the push piece 121 of the actuating rod 12 drives one of the teeth on the gear 32 to move upward shown in FIG. 8. The air in the first extendable air pump 26 is incapable of being sent out via the first discharge pipe 253 due to being controlled by the control valve 31. Hence, every time the hand press lever 11 is pressed down, the sucking disc 5 under the actuating rod 12 presses the pressing spot once and every time the hand press lever 11 is raised, the air can be filled into the first extendable air pump 25. In case of the patient being pressed five times before the hand press lever 11 is raised, the gear 32 can be driven to rotate a revolution and to turn on the control valve 31 such that the first extendable air pump 25 can be compressed by way of the elastic force of the compression spring 24 and the air in the first extendable air pump 25 can enter the mixing chamber 311 to mix with the oxygen from the fourth intake pipe 35. Further, the mixed air can be blown into the mouth of the patient via the air passage pipe 9′ and the mouth-nose breather 8′.

It is noted that the third cylindrical member 23 and the parts therein can be omitted and the second cylindrical member 22 can be joined to the binding device 40 directly. But, two extendable air pumps are utilized can obtain greater amount of filled air.

The invention can perform a procedure of pressing the pressed spot of the patient consecutive five times and admitting air automatically one time to make operation of the cardiopulmonary resuscitation more successfully and conveniently.

The part in mouth-nose breather, which has to contact with the mouth and nose of the patient, can be designed as a disposal part to avoid possible bacteria being infected between the patients.

The invention provides advantages such as the hand pressing filling the a great deal of air, a constant pressing force being obtained to press the heart, the sucking disc fixing to the pressed spot fast, breathing of the patient being capable of being checked with the bubble level gage, hart beating of the patient being capable of being checked with the stethoscope, the mixing chamber in the control valve being capable of mixing the oxygen and the air for increasing the content of oxygen in the air and the pressing ball being capable of supplementing oxygen or fresh air after heart restoring beating.

Furthermore, functions of the present invention such as the patient being bound conveniently, providing simple structure, being fabricated easily, supplying more air filled, supplying the patient sufficient blowing air are not provided in the preceding cited US patents.
